We (3 people) are subletting from a tenant. Earlier, all three of us signed a contract for an apartment with the date and rent, which we paid in full. The tenant then gave only 1 of the members a new contract to sign which would be filed with the landlord. The tenant did not attempt to contact the other two signers to tell them that a new contract was created, so the other two signers believed that they were legally living there. Now, the tenant claims that the other two signers are illegal residents.

Unfortunately additional information is needed to properly answer your questions. Generally speaking, a third party cannot alter, modify, or relinquish the rights of another without their specific authorization. However, some agreements have certain language and provisions that allow just that. For example, a continuing guarantee would be valid as against all original guarantors even if only one of them renewed, or extended the agreement (in this case a lease). Also, if the parties were in breach of the agreement (i.e. behind on rent) the original lease may have terminated on its own terms and then a new agreement could be established with only one of the three original parties.
